Abstract
A process for refining mineral oils by sulfuric acid in which the total fraction extracted from the refined oil is converted into usable sulphonates, a process that allows to obtain purified, deodorized and discolored oils and purified sulphonates, free of mineral salts, extracted without solvents volatile ones of the refined oil and the others of the acidic slimes, the latter in particular in a soluble form in the water and/or in the mineral oils, although they are water-soluble sulfonates, which procedure consists essentially of treating the mineral oils which are to be refined by an appropriate sulfonating reagent under conditions which make it possible to obtain only sulfonic acids apart from the refined oil; in separating, after sulphonation, the treated oil and the acid clay without altering the sulfonic acids; in extracting, from the oil separated after sulphonation or after sulphonation and neutralization, sulfonic acids by precipitation by means of non-volatile products giving a combination and/or an insoluble solution in the refined oil, products such as for example aminoalcohols , polyalcohols, oxyacids sulphonated or not; in extracting, from the acid clay, the sulphonic acids it contains and purifying them by washing with water using an organic extraction product that also acts as a third non-volatile solvent, capable of completing the properties of the sulfonates extracted from the mud in the final product. which is soluble in mineral oils, capable of dissolving perfectly the sulphonic acids contained in said mud and the sulfonates that are derived from them, being the solution obtained soluble in turn in the mineral oils but improper to form a stable emulsion with the water or with the aqueous solutions of acids and mineral salts, under the operating conditions according to the process, that is to say, in particular, at a temperature between 60º and 100º centigrade, the pH being less than 6.
